 Reboot the instance and make sure everything still works. If not, you'll need to automate certain programs to start up on their own (for example, Privoxy will fail to start if OpenVPN does not first create a tunnel interface to bind to).
 
 With this guide, one can set up a fairly secure server with several privacy- and security-enchancing services. The server can be used to circumvent firewalls, provide strong encryption and overall improve your online experience, all for a low monthly cost (average ~$35 per month for a "standard" instance.) A domain name also lets you receive email and assign DNS records, which is convenient, but totally optional.
